Chemokeyp is a feasibility study testing a secure ED-Oncology interface for patients receiving chemotherapy who may present to unscheduled care with possible treatment-related complications.

Participants are enrolled through Oncology and issued a medical-alert-style wristband with a QR code. If they attend the Emergency Department, staff can scan the QR code, access a generic study landing page, and, after SVUH authentication, complete a short structured checklist about possible serious adverse events such as infection, chest pain, vomiting, syncope, or other red-flag symptoms.

The platform is designed as a secure research data-capture portal, not an electronic health record or clinical documentation system. It does not read from or write to the hospital EHR, does not provide clinical decision support, and does not change usual clinical care. Data entered by ED clinicians are limited to predefined structured fields for research and safety-signal feasibility purposes.

The study will assess whether ED clinicians can complete the checklist in real time, whether the information can support earlier notification to the research/trial team, and whether this data accurately corresponds with verified serious adverse events. If feasible, Chemokeyp could help improve communication between Oncology, Emergency Medicine, and trial teams, supporting safer care for patients on chemotherapy and informing future development of ED-oncology digital safety tools.

Inclusion Criteria:

• Patient undergoing treatment for cancer at SVUH

Exclusion Criteria:

• Presence of a condition(s) or diagnosis, either physical or psychological, or physical exam finding that precludes participation (inability to give informed consent)

Patients of SVUH undergoing systemic anti-cancer therapy who may require emergent care during their cancer treatment and who consent to participate.
